Okay, correct me where I am wrong.
If I want zombies to show up and keep them around, I leave a section of my yard open, they can then spawn there and I can enjoy them, feed them or whatever to make them happy.
If I want them to stay out of my yard, to leave my plants alone, I have to lock my yard to all but my household. I can also set aside an area for my plants, lock it to all but household and keep my plants safe.
Okay, this is off topic, I know but what about pets, repairpersons, maids, if I lock it to household only can they get in?
In my other towns, I just take out the gate to my garden untill I want my sims to take care of it, figure it will work here also, keeps them out of the sprinklers.
Do plants grow back, the fruits and veggies, if you leave them out for the zombies?
It seems as if they can be entertaining at times or on the flip side, a royal pain.
